F. Existing Plus Approved Projects (EPAP) Conditions The Existing with Approved Projects(EPAP) scenario is intended to reflect conditions at the "opening day" of the proposed Project. It is also known as Near-Term or Background Conditions. EPAP Conditions are defined as existing traffic volumes plus traffic generated by projects that are approved but not yet built and built but not yet occupied. Other projects in the Project development or approvals process have also been considered in this scenario. The City of Pleasanton's travel demand model incorporates these projects and was the tool used in this analysis.This section presents the results of the level of service calculations under EPAP Conditions both with and without the Project, as well as an alternative scenario that includes the El Charro Road Extension in addition to the Project. Intersection Level of Service Analysis The following presents the specific steps used to develop EPAP No Project scenario forecasts from the City of Pleasanton travel demand model: • Step 1 — Run the Base Year (2015) model to estimate AM and PM peak hour traffic volumes. • Step 2 — Run the Year 2025 model to estimate AM and PM peak hour traffic volumes. • Step 3 —Compare total entering volumes at study intersections to develop growth volumes. • Step 4—Check for reasonableness (e.g., ensure that volumes do not drop below Existing levels, or grow exponentially unless there is a specific reason). Then, to develop a EPAP Plus Project volumes,the following steps were used: • Step 5—Run the Year 2025 model including the Project's land use to estimate AM and PM peak hour traffic volumes. • Step 6—Compare total entering volumes at study intersections with Base Year results to develop growth volumes • Step 7—Check for reasonableness (e.g., ensure that volumes do not drop inexplicably below EPAP No Project levels, or grow exponentially unless there is a specific reason). Finally, to develop volumes for the EPAP Plus Project Plus El Charro Road Extension scenario, steps 5 to 7 were repeated with the inclusion of the El Charro Road extension within the model. The above process relies on the Base Year 2015 model for the estimation of future growth with planned development in the City of Pleasanton. Traffic forecasts within the immediate study area were reviewed to ensure that known developments were adequately reflected in the forecasts. Minor adjustments were made to the forecasts to balance traffic volumes between closely spaced
